To (ZZZ whom it may concern:

Be it known that I, THoMAs Knrrnn NORTH, a subject ofthe King of Great Britain, residing at Vickers House, Broadway, )Vestminster, in the county of London, England, have invented certain new and useful Improvements in or Relating to Metal-Shaping and Similar Machines, of which the following is a specification.

This invention relates to shaping and similar machines and has for its chief object to provide a machine of this kind which is specially applicable for use as a bench shaping machine.

According to the invention the machine comprises a main or tool carrying slide adapted to receive a reciprocating movement by means of a shoe actuated from an eccentric on the driving shaft said main slide being provided or formed with an auxiliary slide which is disposed above and at right angles to the main slide and which is grooved or otherwise adapted to engage positively with the said shoe so as to afford a bearing or guiding surface therefor and enable to and fro motion to be imparted to the main slide.

In order that the invention may be clearly understood and readily carried into effect the same will now be more fully described by the aid of the accompanying drawings, in which Figures 1 and 2 are front and side elevation respectively of a metal shaping machine embodying the invention.

Fig. 3 is a sectional front elevation taken on line aa* of Fig. 2.

Figs. l and 5 are detail views (enlarged scale) hereinafter referred to.

a is the machine frame or standard, Z) the driving shaft and c the fly wheel or pulley iounted thereon. (Z is the main or tool carrying slide mounted to reciprocate in vertical guides (Z, (Z (Fig. 4) in the head of frame and e is the auxiliary slide disposed at right angles to and preferably formed in one with the main slide. The slide 6 thus afiords a sliding surface or path for the shoe 7' which is carried by the eccentric, in such a manner that it moves vertically as well as to and fro along the slide 6 to cause the latter to impart a vertical reciprocating movement to the main slide (Z.

The connection between the slide 6 and shoe is such as to permit of relative movement between these parts while at the same time enabling the slide (Z to be positively raised and lowered under the action of the eccentric. Thus, channel shaped members 0 are provided to embrace the edges of the slide 6 and shoe 7, which members are secured preferably to the slide 6 by screws 6 and while enabling the two parts to rise and descend together they form guides for the shoe The eccentric g is mounted between the bracket like portions a a of the frame a, one of which portions is provided with an aperture or opening sufliciently large to admit of the passage of the shaft and the eccentric. VZith the eccentric in position, a bush It (Figs. 1 and 3) is inserted within said opening to support the shaft 6 at this point, and at the same time maintain the eccentric in position.

The trip gear for disengaging the fly wheel 0 from the shaft as and when required, comprises a pawl 2' mounted in a recess in a plate or disk 7' secured to the shaft Z2, and normally held in engagement with the fly wheel 0 at 0 to effect a driving connection between the wheel and shaft by means of a spring actuated plunger 7" located in a re cess j (see Figs. 3 and 5). The pawl is disengaged by means of a shoe or pawl actuated member is pivotally mounted at 70 between the frame and fly wheel and adapted to engage a lateral projection e" on the pawl i which lies in the same plane as the shoe is (see Fig. 1). The shoe is is brought into operation by a spring controlled cam or lever Z (Fig. 2) capable of being actuated by a rod on connected to a foot or hand lever. The cam or lever Z when operated engages a protuberance or cam surface a on the shoe or pawl actuating member 7a to hold the latter in position for disengaging the pawl 2' from the wheel 0, while for limiting the movement of the cam or lever Z when released under the action of the spring Z, a stop it on the member 70 is provided (see Fig. 5). As shown the spring Z and the rod m 'ill preferably be disposed within the framework of the machine.

What I claim and desire to secure by Letters Patent of the United States is l. in a metal shaping machine the combination with the tool carrying slide, of an auxiliary slide associated therewith, a driving shaft, an eccentric on said shaft, a shoe actuated by the eccentric and engaging said auxiliary slide, and a driving Wheel on the shaft.

2. In a metal shaping machine the combination With the main slide, of an auxiliary slide disposed at right angles to said main slide, a shaft, an eccentric on said shaft, a shoe actuated by said eccentric and engaging the auxiliary slide whereby reciprocating movement is imparted to be imparted to the main slide, and a driving Wheel on said shaft. 7

3. In a metal shaping machine the combination with the main tool carrying slide, of an auxiliary slide, a shaft, an eccentric 1n- .1. 4.

tegral with the shaft and mounted above the auxiliar slide, 'a frame for supporting sald shaft, said frame having a lateral opening therein large enough to permit of the eccen tric being placed in position, a bearing bush adapted to fill said openingv around the shaft, and a drivlng Wheel on sald shaft.

In testimony whereof, I afix my signature.

THOMAS KEPPEL NORTH.
